I belive that for everything on Earth, there is an exact and equal opposite.

Light and Dark
Hard and Soft
Water and Gas ect...
Prove this wrong I challange, I dont belive its possible.
This means to me that life is infinite. Pefect ballance thru evolution.
Evolution is an impefect and often violent process. Morality losses its meaning. The question of good and evil is reduced to one simple choice, Survive or perish.
This way, life will contine forever. No begining. No end.

You want to compare the yearly costs of auto insurance companies. You select a sample of 15 families (some with one and some with multiple drivers). To make the data comparable, certain features, such as the amount deductible and limits of liability, are standardized. The sample information is reported below. At the .10 significance level, can we conclude that there is a difference in the amounts quoted?

For a chemical plant design project for school - I need to find a method to calculate the necessary duty, airflow, and time to regenerate a bed of 3A molecular sieves used to dehydrate a fluid flow. Patent and literature searches have been hit-and-miss for me so far, most just say it takes a few hours with little data behind it. Could point me towards any good resources for this?

Should it be taught better in schools? Finally, would/will humans ever be able to accept evolution over creationism?Are humans ever gonna be able to look at them selves as an evolved organism, and look deeper into this subject, right down to its roots. Should humans do this, do we all beleive that there is a God? Or is this all too complicated for us to understand for now...
